IMPROVEMENT IN MECHANICAL MOVEMENT.

The Schedule refe'n'ed ts in these Letters' Patent and making part of the same.

To all whom tt may con-cern A Be it known that I, DANIEL ZEIGLER, of Lewistown, in the county .of Miiiiin and in the State of Pennsylvania, :have invented certain new and useful Improvementsin Mechanicalv Movement and do hereby declare that the following is a full, clear, and exact ddescription thereof, reference being had to thc accompanying drawingand to lthe` letters of reference marked thereon makinga part of this speciiication.

' The nature of my invention consists in the construction and arrangement of anew mechanical movement, vwhereby a vast increase of power is gained.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, 4 in which.-

Figure l is a longitudinal vertical section, and- Y Figure 2, a transverse vertical sect-ion of my device.

- A represents the frame of my machine, within which is placed, ina vertical position, a'wheel, B provided with cogs or teeth around' its'entire inside circumference.

In suitable journal-boxes on the frame A is placed a shaft, C, provided with a crank,.D, on its outer end, and on its inner end it has a cam, eccentric, or crankpin-E.

' 0n the eccentric Eis placed a wheel, G, provided with cogs or teetlraround its ent-ire outside circumference, the cogs or teeth in this wheel being, however, less in number than those on the wheel B.

-The hub of the wheel. G is made square and projecting on the inner side, so that a square' socket, I,

anch-the cogs on the former being'fof aless number thanthose on the latter, the wheel G will, ofcourse, revolve, revolving-the shaft H with it, whereby a vast increase of power isobtained.

lIf the wheel G has one eogless than the wheel B,

then, for every revolution ot' the eccentric E, the wheel G will be revolved the distance of one cog. If there are two'cogs less, the wheel will turn the-dis' tance of two cogs for each Vrevolution of the eccentric,

and so on until, if' the number of cogs should be one half, then the wheel will make a full revolution for each revolution of the eccentric.

The less difference there is in the number of cogs,

-the more power is gained.

It will bc noticed that, at whatever point the ma` chine may be stopped, the shaft H is perfectly and securely locked; it cannot turnback', it does uotmatter how much weight is attached to it.'

Similar gear-wheels may be added to form connection witha second shaft, or a third, or as many as may be desired, whereby the power may be indenitely increased, althoughthe speed will be proportionately lessened. A

This gearing may be used for an almost endless :va-

riely of purposes, in presses'of every kind, raising buildings, &c. l To increase speed, the power may be applied to the shaft H, when the shalt Gwill be made to rotate with proportionately increased velocity, butV the power is not so great. y

Having vthus fully described my invention,`

What I claim as new, and desire to secure by Let- Witnesses A. N. MARR, A. A. YEATMAN.
